ABSTRACT
Developing responses to human-made climate changes poses enormous challenges to humanity. Present trends of increasing greenhouse gas emissions must be reversed and the emissions radically reduced within a few decades if ‘dangerous climate change’ (Department for Environment, Transport and Rural Affairs, 2006; Hansen et al., 2007) is not to occur. To a great extent, this will require a departure from prevailing technical solutions, political priorities, economic incentives, cultural traditions and ethical judgments.
